fUMPING APPARATUS.

Specification of Letters Patent.

' Patented. Sept. 17, 1918.

Application filed June12, 1917. Serial No. 174,389.

To all whom it may concern:

Be it known that I, GEORGE W. DIGHT, a

Washington, have invented a new, and useful Improvement inPuInping Apparatus,-

of which the following is a specification.

This invention relates to improvements.

in pumping apparatus, and to improvements in means for operating the same, and the object of this improvement is to provide .a

pumpof relatively'cheap and simple form of construction thatis capable of utilizing I the power of water under a small head to pump a lesseramount ofwater to a high elevation. V

Further objects are to. design a pumping device that may be. installed at a comparatively low cost along creeks, rivers and the like where it is desired to pump water to a conslderable elevat on for irrigation or other purposes. 7

,The invention. consists in the novel construction adaptation and combination of parts as will be more clearly hereinafter described and claimed.

In the accompanying drawings Figure 1 is a view in longitudinal cross section of this device showing certain parts in elevation; Fig. 2 is a view in cross section substantially on broken line 2, 2 of Fig. 1; Fig. 3 is a view in cross section of the water wheel and discharge end of the spout or trough for conveying water to the wheel; Fig. 4: is a view in elevation of the wheel shown in Figs. 1 and 4, and Fig. 5 is a view in side elevation of a slightly modified form of the invention.

Referring to the drawings, throughout which like reference numerals indicate like parts the numeral 7 indicates a box or tank that is open at one end and within which this pumping mechanism is disposed, and 8 and 9 are pump cylinders disposed within one end of the box 7 and fixedly secured.

thereto.

10 are pipes that are secured to the pump cylinders and extend upwardly therefrom in axial alinement therewith and 11 are piston rods that extend downwardly through stulfing boxes 12 in caps 13 on the tops of the pipes 11 and are secured at their lower ends to pistons 14 disposed within the cylinders 8 and 9.

The pistons 14 are provided with suitable valves 15 designed to permit water to pass upwardly therethrough, and to prevent water from passing downwardly therethrough and the bottom of the cylinders 8 and 9 are'also' provided with'valves 16 designed to admit water into the cylinders and to prevent water from passing out of such cylinders.

17 are pipes that make connections with the pipes. 10near thetops thereof, as with the caps 13, ,and extend upwardly to any point at which it is desired to deliver water.

18 is-a water wheel that is mounted on a transverse shaft 19 near the outer end of the box 7. The water wheel 18 consists of a plurality of buckets 20 formed and inclosed by walls 21 and each provided with an opening 22 through which water may be received and discharged.

23 is a trough extending lengthwise of the box 7 and having, its discharge end located above the wheel 18 and provided 1 with an inclined slot 24 through which water may be delivered intothe wheel.

The inlet end of the trough 23,-is connected with another trough or water conduit 25 through which water may be carried to and. delivered into the trough 23 and the outlet end of the trough 23 is provided with a slidable gate 26 by which the discharge slot 24 may be closed.

28 are lever arms that are pivoted as at 29 to fixed supports 29, and are connected by slot and pin connections 30 with the top ends of the piston rods 11.

The longer ends of the lever arms 28 extend outwardly into close proximity to the sides of the wheel 18 and are slotted as indicated by dotted lines at 31 and 32 Fig.- 1.

At the termination of the slots 32 the lever arms 28 are each provided with inclined surfaces 33 and 34 for purposes hereinafter pointed out.

The water wheel 18 is provided on one end with two oppositely directed arms 35 that project raidially outward beyond the circumference thereof and on the opposite end with two similar outwardly projecting, oppositely disposed, arms 36 that are arranged substantially at right angles to the arms 35.

Upon the ends of each of the arms 35 and 36 are provided outwardly directed pins or rollers 37 that are adapted to engage within the slots 31 and 32. and with the inclined broken lineg Figt-"l-g im whi'oh positiolr thd lever vvil'l rem-aini -until I the rol-ier- 37 onthe opposite" arm 35 p'ass'es upwardl'y through and in its upvv movement litlits the 'outer wheel shaft 192 end of the lever arm into i11 u11 1;ines; I
